Yosemite Tree Ring Chronology From 70 to -40 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from Upper Yosemite Creek in Yosemite National Park, California. The chronology covers the period from 70 to -40 calendar years before present. This dataset is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate climate models by comparing the proxy tree-ring data with instrumental records for the California region.
• Analyze climate variability and extreme events during the 110-year period covered by the chronology.
• Study forest growth responses to historical environmental conditions in the Yosemite ecosystem.

Strengths

• Data spans a 110-year period (70 to -40 BP), providing a continuous proxy record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, last updated in 1990.
• Specific sample size, measurement methods, and site replication details are unknown from the provided metadata.
